• slatedb

  4 1,249 9.3 Rust

  A cloud native embedded storage engine built on object storage.

  

  Project mention: SlateDB – An embedded database built on object storage | news.ycombinator.com | 2024-10-01

  I don't see any evidence this is implemented in the source code, and the README on Github also marks it as not-yet-implemented. There is an open issue for "design doc for transaction" here: https://github.com/slatedb/slatedb/issues/248 and an open issue for "Add range queries" here: https://github.com/slatedb/slatedb/issues/8

• dbeel

  3 484 9.5 Rust

  A distributed thread-per-core document database

  Project mention: Building an open source vector database. Looking for advice. | /r/rust | 2023-12-07

  If you want some code examples, I wrote a db in rust that might help you: https://github.com/tontinton/dbeel

• ZoneTree

  9 345 8.2 C#

  ZoneTree is a persistent, high-performance, transactional, and ACID-compliant ordered key-value database for .NET. It operates seamlessly both in-memory and on local/cloud storage, making it an ideal choice for a wide range of applications requiring efficient data management.

  Project mention: Show HN: WAL Implementation in Golang | news.ycombinator.com | 2024-07-08

  This reminds me of a ZoneTree which is persistent LSM tree project based on top of WAL, written in C#: https://github.com/koculu/ZoneTree

  Kind of like RocksDB.

• fjall

  1 435 9.8 Rust

  🗻 LSM-based embeddable key-value storage engine written in safe Rust

• pgrocks-fdw

  1 122 10.0 C

  Bring RocksDB to PostgreSQL as an extension. It is the first foreign data wrapper (FDW) that introduces LSM-tree into PostgreSQL. The underneath storage engine can be RocksDB. The FDW also serves for VidarDB engine, a versatile storage engine for various workloads. See the link for more info about VidarDB engine.

  

• LSM-Tree

  2 76 7.4 Java

  Log-Structured Merge Tree Java implementation

  Project mention: Log-Structured Merge Tree implementation | /r/coolgithubprojects | 2023-11-15

• udisk

  1 57 1.8

  The fastest ACID-transactional persisted Key-Value store designed as modified LSM-Tree for NVMe block-devices with GPU-acceleration and SPDK to bypass the Linux kernel

  

  Project mention: Ask HN: Why are there no open source NVMe-native key value stores in 2023? | news.ycombinator.com | 2023-10-16

  I don't remember exactly why I have any of them saved, but these are some experimental data stores that seems to be fitting what you're looking for somewhat:

  - https://github.com/DataManagementLab/ScaleStore - "A Fast and Cost-Efficient Storage Engine using DRAM, NVMe, and RDMA"

  - https://github.com/unum-cloud/udisk - "The fastest ACID-transactional persisted Key-Value store designed for NVMe block-devices with GPU-acceleration and SPDK to bypass the Linux kernel."

  - https://github.com/capsuleman/ssd-nvme-database - "Columnar database on SSD NVMe"

• kivi

  Dynamo-inspired distributed leader-less key-value database that has no unique features and no apparent reason to exist

• gosqldb

  1 27 10.0 Go

  A key-value persistent database that supports SQL queries over B+ and LSM trees

• lsmtree

  1 25 1.7 Go

  Log-structured merge-tree (by krasun)

• NoSQL

  2 0 8.1 Rust
